Both art and content are valuable, and can serve the same purpose, but they aren't the same thing.

Art is messy, emotional, not guaranteed to be successful and difficult to measure. Content is a part of a larger strategy to stake claim to people’s eyeballs, ears, emotions and usually, wallets. Art can be so good and emotionally effective that it becomes great content. Although there are numerous online gurus teaching people how to make good content, grow your email list and increase traffic, followers and fans, even getting a successful content strategy in place is more art than science.

Personally I'm getting tired of content, but I never get tired of art. Content tells us how to live, art shows us how to live.
